Definitions

  • the invention relates to a hob with a cover plate and at least two heating zones according to claim 1.
  • an induction hob with four heating zones is known in which the heating zone is not marked.
  • Sensor and control means are provided for the detection of a cookware element extending beyond the edge of a heating zone or for the detection of a large cookware element which overlaps with several heating zones.
  • the DE 102 07 183 B4 further teaches to design the induction coils in such a way that the entire surface of the hob is filled as much as possible, so that inactive areas of the hob are avoided as far as possible.
  • a device for determining the location of cooking appliances on a hob which has a plurality of heating elements which are distributed in a matrix-like manner below a heat-resistant / heat-resistant surface on which the cooking appliance can be randomly placed.
  • Each heating element can also act as a magnetic field transmitter.
  • the device comprises loops which are arranged essentially around parts / sections of the matrix of heating elements and function as magnetic field receivers. The loops each have conductors arranged between each pair of adjacent heating element columns or rows. Connection means are provided to connect each loop to a detection circuit.
  • EP 2 180 760 A1 is already a method for detecting the presence of a cooking vessel on an underneath a glass surface arranged induction heating element known.
  • the method includes detection by a conductor electrode placed under the glass surface when a cooking appliance is placed on the induction heating element, by measuring an electrical capacitance. The user is shown whether the cooking appliance is present on one or more induction heating elements. After activation by the user, a second detection of the cooking appliance is carried out in that energy is supplied to this induction heating element and at least one electrical parameter is estimated by its power circuit.
  • a “cookware sensor unit” is to be understood in particular as a unit which is provided to determine at least one parameter with information about the cookware element.
  • the cookware sensor unit preferably has at least one cookware sensor.
  • the cookware sensor unit particularly preferably has one cookware sensor per heating zone. Alternatively or in addition, the cookware sensor unit could have at least one further cookware sensor outside the heating zones.
  • the cookware sensor unit is preferably designed at least partially in one piece with a control and / or regulating unit of the heating zones.
  • the cookware sensor unit has at least one bridging detection unit, which is provided to detect at least one bridging of the at least two heating zones by means of at least one cookware element.
  • a “bridging detection unit” is to be understood in particular as a unit which comprises at least one evaluation unit and / or a special sensor for detecting the bridging.
  • the bridging detection unit is preferably designed at least partially in one piece with the control and / or regulating unit of the two heating zones.
  • a “bridging” should be understood to mean a material connection between the two heating zones by means of the cookware element.
  • “Provided” is to be understood in particular as specifically programmed, designed and / or equipped.
  • the hob device has a control and / or regulating unit which is designed to operate the two heating zones in a coordinated manner, at least depending on the cookware sensor unit, whereby particularly convenient operation and particularly efficient operation can be achieved.
  • the operating frequencies of the inductors can be matched to one another in order to avoid destructive interference and / or humming of the hob.
  • control and / or arithmetic unit is useful for a person skilled in the art when bridging at least one operating parameter, for example an induction frequency, a heating power, a heating period and / or another operating parameters appearing, of at least one of the heating zones adapts to another of the heating zones and in particular equates them.
  • operating parameter for example an induction frequency, a heating power, a heating period and / or another operating parameters appearing
  • the bridging detection unit has at least one cooking utensil sensor, which is provided to detect a cooking utensil element in an inactive area of the cover plate between the two heating zones, which enables particularly simple detection.
  • An “inactive area of the cover plate” should in particular be understood to mean an area which is arranged outside a heating zone.
  • the control and / or regulating unit is advantageously designed to respond to the simultaneous response of the two cookware sensors arranged within the two heating zones and the at least one further cookware sensor arranged between the two heating zones to operate the two heating zones in a coordinated manner.
  • An asymmetry in the detection can be avoided if the at least one further cookware sensor is at the same distance from the two centers of the two heating zones.
  • a particularly reliable detection can take place if the hob is equipped with at least two further cooking utensil sensors, which can be arranged in particular symmetrically to a line connecting the two center points of the two heating zones in the inactive area of the cover plate outside the two heating zones.
  • the further cookware sensor is elongate and is arranged transversely to a connecting line of the two center points of the two heating zones in the inactive area of the cover plate outside the two heating zones.
  • the hob has a hob device with a cookware sensor unit 28.
  • the cookware sensor unit 28 has cookware sensors 20a to 20d and a cookware sensor unit 28.
  • the cookware sensors 20a to 20d are arranged in the center of the heating zones 10a to 10d or the heating elements 12a to 12d, which preferably comprise induction coils, but can also work capacitively or optically in alternative exemplary embodiments of the invention.
  • the cookware sensors 20a to 20d provide a parameter with information about a cookware element 18a, 18c, 18d placed on the respective heating zone 10a to 10d.
  • the cookware sensor unit 28 has a bridging detection unit 30 with signal coupling means and an evaluation unit 32.
  • the evaluation unit 32 is partially formed in one piece with a control and / or regulating unit 26.
  • the signal coupling means are designed in one piece with the cookware sensors 20a to 20d, but could alternatively also be designed separately.
  • the signal coupling means couple a signal to a cookware element 18a, 18c, 18d.
  • the signal is designed as an inductive signal.
  • the cookware element 18a forwards the signal. If the cookware element 18a bridges two heating zones, the cookware sensor 20a to 20d of one of the heating zones 10a to 10d detects the signal of a signal coupling means of another of the heating zones 10a to 10d. Alternatively or in addition, a cookware sensor in one heating zone could also detect a heat temperature in another heating zone.
  • the evaluation unit 32 detects the coupling of the energy.
  • the bridging detection unit 30 is thus provided to detect crosstalk of energy from one of the heating zones 10a to 10d to another of the heating zones 10a to 10d.
  • a further cookware element 18b is arranged on the heating zone 10c, the diameter of which essentially corresponds to the diameter of the heating zone 10c.
  • Fig. 2 shows the two heating zones 10a, 10b of the hob Fig. 1 in a detailed representation.
  • the bridging detection unit 30 includes two further cookware sensors 22a, 22b.
  • the other cookware sensors 22a, 22b are outside of the Edges 14a, 14b arranged below the cover plate 16 made of glass or glass ceramic in an inactive area of the hob.
  • the further cookware sensors 22a, 22b are at a distance of approx.
  • the two further cookware sensors 22a, 22b are arranged symmetrically to a connecting line 24 between the centers of the two heating zones 10a, 10b.
  • Fig. 3 shows the in Fig. 2 shown section of the hob in a configuration with two cookware elements 18c, 18d, the diameter of which does not or only slightly exceeds the diameter of the relevant heating zone 10a, 10b and which are set up in the middle of the heating zone 10a, 10b.
  • the two further cookware sensors 22a, 22b are therefore not covered by the bottom of the cookware elements 18c, 18d, so that they do not respond.
  • the cookware sensors 20a, 20b arranged in the center of the heating zones 10a, 10b, on the other hand, are completely covered by the base of the respective cookware element 18c, 18d, so that these cookware sensors 20a, 20b respond.
  • the schematically illustrated control and / or regulating unit 26 picks up the signals from the cookware sensors 20a to 20d and 22a, 22b in order to identify on which of the heating zones 10a-10d a cookware element 18c, 18d is placed or whether a large, elongated cookware element is possibly 18a from the in Fig. 1 illustrated type covers both heating zones 10a, 10b.
  • the control and / or regulating unit 26 concludes from the fact that the two further cookware sensors 22a, 22b do not respond, that two individual, independent cookware elements 18c, 18d are placed on the two heating zones 10a, 10b.
  • Fig. 4 a configuration is shown in which an elongated cookware element 18a designed as a roaster is placed on the hob in such a way that both heating zones 10a, 10b are covered. Both the cookware sensors 20a, 20b within the heating zones 10a, 10b and the cookware sensors 22a, 22b outside the active areas of the heating zones 10a, 10b respond. From this, the control and / or regulating unit 26 ( Fig. 1 ) from the fact that not two independent cookware elements, but only a single cookware element 18a is set up, which covers both heating zones 10a, 10b.
  • the control and / or regulating unit 26 operates the two heating zones 10a, 10b in a manner that is coordinated with one another, in particular with the same heating frequency and / or the same surface heating power.
  • the heating power for heating the cookware element 18a can be selected by the user through a single input with a single operating element.
  • the heating zones 10a, 10b are combined to form a common, large heating zone.
  • the control and / or regulating unit 26 can visualize the assignment of the operating element to the combined heating zone, for example via a display.
  • the further sensors 22a, 22b can be arranged between a specific pair of heating zones 10a, 10b or, alternatively, between each pair of adjacent heating zones 10a-10d.
  • Figure 5 shows two heating zones 10a, 10b of a hob with an elongated sensor 22c arranged between the heating zones 10a, 10b according to a further embodiment of the invention.
  • the sensor 22c replaces the two further cookware sensors 22a, 22b from the Figures 2-4 .
